HYDROCARBON OR GASOLENE TURBINE-MOTOR.

Application filed March 4, 1919.

To all lwhom it may concern.'

Be it known that I, WILLIAM G. SIMPSON, a citizen of the United States,residing at 1666 Brush street, in the city of Detroit, in the county ofWayne and State of Michigan, have invented a new and useful Hydrocarbonor Gasolene Turbine-Motor,.of which the following is a specification.

This invention relates to new and useful improvements in explosiveturbines and has for an object provision of a-device of this character,simple of construction and parts of which are readily replaced.

A further object is a provision of the above character wherein theentire effective energy of explosion is exerted upon the vanes of theturbine. l

Other objects andadvantages will be ob, vious during the course of thefollowing discussion.

lIn the drawings wherein for the purpose of illustration is shown thepreferred embodiment of my invention, and wherein like numeralsdesignate like parts thereat. The figure is a transversel sectionthrough my turbine.

Referring now more particularly to the drawing, the numeral l indicatesa casing having end closures 2 and 3.

A shaft 4 is mounted within the casing in suitable bearings 5 and 6.Intermediate these bearings the shaft is provided with a sleeve 7,having eccentrics 8 and 9 formed thereon.' The sleeve 7 is provided witha keyway 10 for a purpose hereinafter 'to ap-A pear. y.

Secured to the shaft 4 is a gear 11 mounted in a bearing 12 formed inthe end plate 3 of the casing is a stub shaft 13. Mounted upon thisstub'rshaft is a gear 14 meshing with/the gear 11 upon shaft 4. Securedto the gear 14 is a gear 15, which meshes with a gear 9 rotatablymounted upon a shaft 4. The gear 9 is provided with keys adapted toenter the keyway 10 formed in the sleeve .7.`

Formed in the casing 1 is a cylinder-16 within which is mounted a piston17 connected `by a pitman 18 to the eccentric strap 19, which in turnreceives eccentric 8. An intake chamber 20 is provided in casing 1. Thecommunication between the intake chamber and the cylinder is closed bymeans of a puppet valve 21, the stem 22 of which is adapted tojbecontacted bythe eccentric 9 on vthe sleeve 7 at each revolution thereof.

Specification of Letters Patent. Patented .Blay 11 192() Serial N.280,593.

A valve 23 governed by a dash-.pot of any suitable construction closescommunication between the rcylinder 16 and chamber 25. This chamber 25is provided with a reduced nozzle or opening directed against vanes 27,secured to, or formed'upon a fly wheel 26 secured to the shaft 4.

Secured to the gear y15 is a bevel gear 28 which meshes with a bevelpinion 2O adapted to operate a timer 30 of any suitable construction.

`The operation of my device is as follows:

The shaft 4 is rotated until the charge is drawn into the cylinder andcompressed, when it will be exploded in the usual manner. The spring ofthe dash pot is set at a suitable point slightly higher than the pointof compression in the cylinder 16, that is to say, if the point ofcompression in the cylinder 16 is 70 pounds the dash-pot spring is setat 75 pounds or thereabout.4

`It will readily be seen that under the force of the explosion thedash-pot valve is opened and the exhausting gas impinge against thevanes of the fly wheel rotate the same.

It will readily be seen that as long -as the pressure within the chamberremains at more than 7 5 pounds the dash pot actuated valve will remainopen and exhaust continue. As soon however, as the pressure drops belowthis point, this valve closes and the cycle is again repeated. Bysupplying a suitable governor for the dash-pot, and the timer, theoperation of the turbine may be governed so that the number ofexplosions are entirely under control of the operator. It will ofcourse, be understood, that some suitable means for, disconnecting thetimer during the period at which vthe dash-pot valve'is open mustl besupplied.

It is to be understood that the form of my invention herein shown anddescribed is to be taken as the preferred embodiment ofl the same andthat various changes in the shape, size and arrangement of parts may beresorted to without departing from the spirit of the invention or thescope of the subjoined claims.

v'What I claim is,

1. In a device of the type describedfa casing, a shaft rotatably mountedwithin said caslng, a sleeve rotatably mounted upon said shaft, areducing gear train connecting said shaft and said sleeve and eccentriccarriedl by said sleeve, a cylinder formed in Said casinggva pistonreciprocable therein, means connecting said piston and said eccentricwhereby saidl piston `is reciprocated when said sleeve is rotated, meansVfor supplying a combustiblecharge to said cylinder, an exhaustavalvcfor said cylinderv adapted to' be opened When the 'pressure in saidcylinder exceeds the compression pressure thereof -said casing, a pistonreciprocable therein, -means connectlng sald pistonl'and sald eccentricwhereby said piston is reciprocated when said sleeve is rotated, meansfor sup'- plylng a combustible charge to said cylinder, a dash-potcontrolled exhaust Valve for v said cylinder adapted to be `opened whenthey y pressure in said cylinder. exceeds the compression pressurethereof, and a fly Wheel secured to said shaft provided with vanesdisposed in the path of said exhaust.
